Application filed June as,

To all whom it may concern]:

Be it known that 1, CHARLES S. SHALLEN- BERGER, a citizen of the United States, residing at the city of St. Louis and State of Missemi, have invented certain new end useful 1m; rovements in Brohefihoes, of which the following is at specification.

The invention relates to such improvements and oonsists of the novel con truction and combination of parts hereimiiter described end subsementiy claimed.

Reference may 'e lied to the accompanying drawings, and the reference characters which form a. port of this s eoificetion. Simiier characters refer to similar orts in the severed figures therein.

This invention relates to broke-shoes suitable for use on railway cars, and consists of o face-insert of comparatively-herd metal, a heokdiise t comprising o ductiie metal plate provided with strengtheniog angle-flanges, on attesting ioop or hey-Way secured to the middie yortiori. of the beak-insert, end it metei hody oest upon such inserts, with the keyevey projecting therefrom, and the inserts is contact with eeeh other.

The object oi the invention is to reinforce end strengthen the casting to permit the wearing sway of e considerable portion of the easting without danger hreehiog 1 Wise injuring the shoe, all. of which "ully described and subsequeritly pointed out in the claims.

- form of back-insert is a. top plan view the drawings is a view in per Fig.

Fig. 5 is a view in perspective of a. modified detached. Fig. 6 is o. view in perspective oi e modified l'orm oi key-my attachment. Fi 7 is a transverse section token at the midoie of s. completed brake-shoe, showing a modified form of back insert and key-Way attachment.

The beck-insert, 1, is o ductile metztiplote bent to form the oppositely disposodimgld flanges 2 and The body port of the pinto which connects the two hinges may be given any desired cross-sectional form, mod the some is shown with three plane surfaces, 4, and 6, singularly disposed rohttiwly to our other and to the ztnglodhmges as shown. The plane surfaces, -'l-, 5 zmd (i, may be pro vided with any desired number of :Lpil'l un s,

7, 3 theret n'ough, when the esting is formed about the inserts. I

A for, -insert, 10, is shown iii moss-section in This insert may he of any known form. The heck-insert is made :1 little narrower than the face-insert, and the two in-' to, 'iermit the ready flow oi molten metal disturbance of the relative positions of then hoth to each other and to the mold i1 formed. The loop or has rte, which the casting is iiddle sert, and Us hoot over thereon, as shown in is shown :1 modified form of Pia-'56 forming the hock-insert, plate is so hon-t as to form oppo- .,ed angle-flanges, 20 and 21, on then'iselves, and ogion bent 1 flanges, 22 and 23, forming *itensions oi the body, 24,

but sepedn from by the grooves, 25 and formed by the flanges, 20 and 21.

'iheedge flanges, and 23, are provided with the apertures 27, adapted to receive the etteohing iugs oi the keywoy.

A. suit-ahie key-Way attachment, 30, is G. This key-way consists of shown is. Fig. a plate o'r sheet-metal, shtted at the ends to form lugs, 31 and 32, and bent to substantislly the lUIDI shown in Fig. 6.

I The lugs 31 and 32 are then respectively inserted in the apertures 27 and Gent over against the lower sides of the e e l lo res 22 and 23, as shown in Fig. thereby lu mly securing the key-way to the insert.

The iosertqointc may he provided with any desired number of apertures, 33, to permit the flow of molten metal tllorethrough when the ousting is formed about the i1 sorts.

rt'hon desired, the kovovay attachment 21m he roini'ouwod by strengthening ribs, 40, as shown iuFigs. 2 and 4.

What i vlnirs. as new and desire to sol-um hy Letters Patent isl. in 1!, lu'nlio-slmo, a. lnuxk-insert comprisis secured to the metal part of sert hy means of the lugs, 16, ro-

mite inner side, and adapts toenter the n.- aperture, 1?, in the hack-in- I ing a ductile metal plate having its side edges bent to form oppositely disposed grooved angle-flanges extending long1tudi- 'nally of the shoe; an attaching loop or l eyway; and means for securing the key-Way to the middle portion of. the angle-plate; in

combination with a cast-metal body.

- oppositely disposed angle-flanges, and aper-- tured at its middle portion toreceive the attaching lugs of a key-way attachment; a keyway attachment provided with attaching lugs adapted to enter a plate aperture and be secured therein; and a cast-metal 3. In a brake-shoe, the combination with a metal face-insert; ofa back-insert comprising a ductile metal plate having its side edges bent to formroppositely disposed angleflanges, with the face ed es of-the flanges in engagement with the back of the face insert; a key-way; means for securing the same to the back-insert; and a metal body cast u on such inserts.

4, n aibrake-shoe, the combination with a face-insert; of a back-insert comprising a ductile metel plate having oppositely disposed side supports in engagement with the 1 back of the face-insert; and a metal body cast upon such inserts.

In testimony whereof, I have hereunto set my hand this 12th day of June, 1908.
